Robotcaptcha.info is adverse domain, that may show unwanted pop-ups and ads in Google Chrome, Mozilla Firefox, Internet Explorer Safari or Edge browsers on Windows, Mac or Android operating systems. Landing pages from Robotcaptcha.info appear from nowhere and offer users to subscribe to notifications. This is feature in modern browsers, that help users get actual news in faster and convenient way. However, on the other side of this, when website is of advertising nature, users start receiving ads, pop-ups, tech support scam messages on their desktops. This is an element of social engineering, and clicking “Allow” button, actually, subscribes users to notifications. At the same time, Robotcaptcha.info initiates standard dialog box window with option to allow or block notifications from site you are visiting. If person clicks on the “Allow” button, users will start receiving unwanted pop-up ads from Robotcaptcha.info directly on the desktop even when browser is closed.
